Answers

Answer:

-[tex]17^\circ F[/tex]

[tex]17^\circ F[/tex] decrease in the temperature.

Step-by-step explanation:

Given that:

Temperature at the night = [tex]12^\circ F[/tex]

Temperature in the morning = -[tex]5^\circ F[/tex]

To find:

The total difference in the temperature = ?

Solution:

Difference of any quantity is given by the Final value of quantity minus Initial value of quantity.

Therefore, the difference is given as : -[tex]5^\circ F[/tex] - [tex]12^\circ F[/tex] = -[tex]17^\circ F[/tex]

Negative value in the difference indicates that there is a decrease of the quantity.

So, the answer is:

-[tex]17^\circ F[/tex]

there is decrease of [tex]17^\circ F[/tex] in the temperature.

The Value of K is 28
Here
First when we solve the left side
Which is (25*20)+(25*8)
Here it comes (500)+(200)
So 500+200= 25*K
700 = 25K
700/25=K
k=28
We can also just take out 25 common and do 20+8
Like
(25*20) + (25*8)
Here take 25 as common
25(20+8)
=25*28 = 25K
25*28/25 = K
25 cancels out 25
K=28

while holding her cat, Mya steps on a scale, the scale reads 127 pounds. Alone, Mya weighs 112 pounds. Write an addition equation to find the weight of Mya's cat.

Answers

Answer:

127+(-112)=15

Step-by-step explanation:

If you subtract 112 from 127, you can find the difference. Since 112 is Mya's weight, and the total is 127, we need to find out how much weight is left over after we take away Mya's weight, which would be the cat's weight. So if you follow the expression, which is 127+(-112), you would get a sum of 15 pounds. Since this is an addition problem, the expression would be 127+(-112) instead of 127-112. I hope you understand. The difference between 127 and 112 is the cat's weight, so the cat weighs 15 pounds.

If the graph of the line passes through the origin, it means that the graph has no y-intercept

Step-by-step explanation:

To rent a certain meeting room, a college charges a reservation fee of $38 and an additional fee of $6.80 per hour. The history club wants to spend less than $65.20 on renting the meeting room. History club wants to spend less than $65.20 on renting the meeting room. What are the possible amounts of time for which they could rent the meeting room? Use t for the number of hours the meeting room is rented, and solve your inequality for t.

Answers

Answer:

t < 4

Step-by-step explanation:

Reservation fee = $38

Additional fee per hour = $6.80

The history club wants to spend less than $65.20 on renting the meeting room.

t = number of hours the meeting room is rented

The inequality is

38 + 6.80t < 65.20

6.80t < 65.20 - 38

6.80t < 27.20

t < 27.20 / 6.80

t < 4

Therefore, number of hours the meeting room is rented should be less than 4 hours

What is the mZACB?
O 10°
B
O 50°
(4x)
O 90°
O 180°
(7x-20)
C

Answers

Answer:

50 degrees

Step-by-step explanation:

The total sum of angles in a triangle is 180, thus the value of ∠ACB will be obtained as follows:

Given that the triangle is a right triangle, the sum of angles will be:

(4x)°+(7x-20)°+90=180

simplifying and solving for x we get:

4x+7x-20+90=180

11x=180+20-90

11x=110

dividing both sides by 11 we get:

(11x)/11=110/11

this gives us

x=10°

Thus substituting the value of x in:

∠ACB=(7x-20)°

=(7*10-20)

=70-20

=50°

Answer: 50°
